Application tiled June 5| 1907. Serial No. 377.334.

To all whom it may concern:

Be it known that I, EDWIN E. SLICK, of l, Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Bar-Handling Apparatus, of which the following is a full, clear, and exact description, reference bei G had to the ,accom anying drawings, fcrmmg part of this speci cation, in which-.-

Figure 1 is a side elevation partly in section showing one lform of my improved appaand Figs. 3 and 4 are detail views ofthe scrap chute and scrap car.

My invention relates to the handling o l Iilietal bars, strips dac., such as tin bar and s el Tiie object of the invention is to provide a simple and cheap apparatus for handling the scrap ends and piling and removing the bars.

In the drawings, 2 represents the lower shear blade of a shear having a feed-out chute 3 for the crop-ends. This chute 3 discharges into two receptacles 4 and 5 mounted upon each of the wheeled trucks or cars traveling u on track 7. rlhe lower end portion of the c ute is slotted as shown at 8, this slot extending across the chute loor and being positioned over the receptacle 4. As the cut-oit` ends slide down the chute, crop-ends and pieces of short and unmarketable length will rop through the slot 8 into the receptacle 4. Those ends which are of sullicient length to be marketable will bridge the slot S and drop from the end ofthe chute into thtl receptacle 5. When the boxes 4 and 5 become filled with crop-ends and short bars or plates, the trucks carrying the boxes are Ishifted on the track 7 until the boxes 4, .5 are beneath the chute 3 and the boxes 4, are in the position shown by dotted lines, where they can and trucks by the overhead crane and emptied or deposited at any desired point, and empty boxes can the car or truck. When the receptacles 4, 5l become iilled the-cars are then shifted in the opposite direction, thus bringing the iilled boxes into position to be removed by the crane and at the same time shifting thc empty boxes on the other car into position beneath the chute 3. The sheared-of bar lies durirnr the shearing operation upon the shear table. I have shown this table as comprising rollers 9 with side uides 10 between them, the rollers being rivcn from the line shaft 11 through bevel In order to provide for simultaneous shearing of two or more bars, and also to provide for taking up several piles of bars, to give the crane a proper load I preferably rovide vertically extending separators w iieh divide the skelp or bars on the shear table. Thus, the apron plates 13 between the rollers 9 are shown as provided with vertically extending separators 14; and the fore plate 15 of the shear is also provided with simil ar separator ribs 16.

At the outer end of the shear table is placed a stop 17, which I have shown as pivoted to the rock shaftlS, having a counterweighted rock arm 19 connected by thepivotal link 2() with the piston or plunger 21 oi a vertical hydraulic cylinder 22. By actuating this cylinder the stop may be raised or lowered to either hold the bars on the shear table, or allow them to be fed forward to and between the pinch rolls 23 and 24. The upper pinch roll is preferably spring-pressed downwardly, and the lower roll may be driven by bevel gear connections 25 leading to the shaft 11 which is driven through slowmotion gearing connections 26 to an electric motor 27. This motor is rovided with the usual controller by which 31e pinch rolls and table rollers may be driven at the proper times.

At the end of and in line with the shear table is the metal piler. I have shown this as consisting of a series of bed lates or castings 28, which are arranged en wise in a row, each being provided with the vertically extending partitions 29 which divide the skelp or bars into four piles. The bed plates or castings are spaced apart at their adjacent ends, and in these spaces are located the lifter bars 30 carried on horizontal support 31, which may be lifted by a crane attached to ring 32. 'lhis crane may be of the ordinary traveling or jib type.

In using the a paratus, the skelp or bars are fed forward y from the mill between shear blades and upon the shear table. The front end of the bars are first cropped, these crop-ends sliding down the chute 3 and droping through the slot 8 into the box 4. The )ars are then fed forward until they strike the stop at the extreme end of the shear table. Two or more plates may be fed forward in the different positions, and these ma be sheared simultaneously. The rear en s of the plates or bars are then sheared l and the ends dropdown the chute, and are fed automatically into either the receptacle 4 or the receptacle 5, thus selecting them either for recharging or for sale. After cutting oil", the cylinder is actuated to lift the Each bar or set of bars passing through the pinch rolls will drop upon the next preceding bar or set of bars. in the piler, until the desired number of bars are piled. A crane may then be connected to the lifter, 'and the several pilesof skelp or bars may be lifted and taken to the desired point.

The advantages of my invention result from the selective action of the scrap chute, fromlthe peculiar arrangement of the stop, and pinch rolls, and also the arrangement of the separators for producing several piles of the bars or skelp side by side. By the use of two or more cars carrying the receptacles 4, 5 on the depressed track 7, the scrap receptacles are always .in 'position beneath the chute to receive the sheared ends. The filled scrap receptacles are easily and quickly removed from the cars by'means of the overhead crane, which deposits the boxes or unloads them at any point within range of the crane.

Many changes may be made in the form and arrangement of the shears, tables and pinch rolls, &c., without departing lfrom my invention.

I claim:-

1. In bar handling apparatus, a shear havinor a table in front thereof, a feed chute below said table, said chute having a slot or opening adapted to selectthe shorter pieces and divide them into two piles substantially as described. l

2. The combination with a shear having a feed table in front thereof,.of a chute leading from said shear below said table, a car having receptacles into which the chute discharges, and a slot or' opening in the chute arranged to separate the shorter pieces and ,drop them into one of the receptacles, substantially as described.
